A check shows the malice hasn't moved at all! It's as if it's biding its time. Waiting. Its eyes look right at Zuko and Sheila.

It's as if it's waiting for them to make a move...and has no hurry at all. It probably knows they arrived here from the rail outside, and knows they have no other way to move somewhere else. And even then, it stays down there, waiting.

It's not confidence in its skills. It's...like an ambush predator staring at four mice near its den, ready to spring into action at the right moment.

How unpleasant.
